[0019] The utility model provides Figure 1-3The automatic hoisting device for a washing machine assembly line shown in the figure comprises an I-shaped hanging rail 1 and a sliding mechanism 2 arranged at the bottom of the I-shaped hanging rail 1, the sliding mechanism 2 can slide back and forth on the I-shaped hanging rail 1, a transmission chain 3 is arranged at the bottom of the sliding mechanism 2, a telescopic hoisting device 4 is arranged at the bottom of the transmission chain 3, and a hoisting hook 5 is arranged at the bottom of the telescopic hoisting device 4. The I-shaped hanging rail 1 and the transmission chain 3 can be arranged into a circular structure according to the direction of the washing machine assembly line, and the left and right ends of the I-shaped hanging rail 1 of the circular structure are both semicircular, and the transmission chain The strip 3 can be driven by the transmission gear on the washing machine assembly line. The sliding mechanism 2 is composed of a connecting rod 6, a U-shaped sliding sleeve 7 and a sliding roller 8. The U-shaped sliding sleeve 7 is sleeved on the outside of the industrial hanging rail 1 with its opening facing upward. The front and rear ends of the opening of the U-shaped sliding sleeve 7 are connected with sliding rollers 8 through a rotating shaft. The two sliding rollers 8 are respectively located inside the industrial recesses at the front and rear ends of the industrial hanging rail 1. The bottom of the U-shaped sliding sleeve 7 is fixed with a connecting rod 6 by screws, and the bottom of the connecting rod 6 is fixedly connected to the transmission chain 3 by screws. The sliding roller 8 can be on the industrial hanging rail The lifting device 5 is used to lift the washing machine accessories and the lifting hook 5 is used to lift the washing machine accessories.
[0020] like Figure 1 and Figure 3As shown, the telescopic lifting device 4 includes a metal telescopic frame 14, a telescopic hole 15 and a metal hanging rod 16. The metal hanging rod 16 is fixed to the bottom of the transmission chain 3 by screws. The metal telescopic frame 14 is provided with a telescopic hole 15, and the telescopic hole 15 opens upward. The telescopic hole 15 is sleeved on the outside of the metal hanging rod 16, and the metal hanging rod 16 can move up and down in the telescopic hole 15. The telescopic lifting device 4 also includes a connecting shaft 9 and a hook groove 10. The hook groove 10 is provided inside the bottom end of the metal telescopic frame 14. The right end of the lifting hook 5 is inserted into the hook groove 10, and the right end of the lifting hook 5 is connected to the metal through the connecting shaft 9. The telescopic frame 14 is rotatably connected, and the telescopic lifting device 4 also includes an anti-slip fastening screw 11, a fastening nut 12 and a telescopic anti-slip groove 13. The telescopic anti-slip groove 13 is arranged inside the left and right ends of the metal telescopic frame 14, and the telescopic anti-slip groove 13 is vertically arranged inside the metal telescopic frame 14. The left and right ends of the bottom of the metal hanging rod 16 are provided with anti-slip fastening screws 11, and the two anti-slip fastening screws 11 respectively pass through the two telescopic anti-slip grooves 13, and the outside of the two anti-slip fastening screws 11 are threadedly sleeved with fastening nuts 12, and the two fastening nuts 12 are respectively located on the outside of the left and right ends of the metal telescopic frame 14.
[0021] like Figure 1 and Figure 3 As shown, when the lifting height of the lifting hook 5 is too high or too low, if the lifting hook 5 is not adjusted at this time, it will easily cause lifting failure, or it will easily cause the washing machine accessories to collide with the washing machine assembly line after being lifted, so it is necessary to adjust the telescopic lifting device 4 to change the lifting height of the lifting hook 5. When adjusting the telescopic lifting device 4, it is first necessary to lift it at the bottom of the metal telescopic frame 14, and then it is necessary to use an adjustable wrench to loosen the two fastening nuts 12, so that the two fastening nuts 12 are changed from the state of tightly contacting the outer walls of the left and right ends of the metal telescopic frame 14 to a disengaged state, and then the metal telescopic frame 14 can be moved up and down. When the metal telescopic frame 14 moves up and down, it will move up and down on the outside of the metal hanging rod 16 through the telescopic hole 15, and the two anti-slip fastening screws 11 are respectively on the two ends. The two fixing nuts 12 are tightened synchronously in the telescopic anti-slip grooves 13, ensuring that the metal telescopic frame 14 and the metal suspension rod 16 can be normally telescopically adjusted. Because the anti-slip fastening screw 11 is inserted in the telescopic anti-slip groove 13, the metal telescopic frame 14 and the metal suspension rod 16 can be prevented from being separated, ensuring that the two are always in a connected state. After the metal telescopic frame 14 moves up and down to the optimal height, it is necessary to maintain the height and use an adjustable wrench to retighten the two fixing nuts 12 so that the two fixing nuts 12 are tightly against the outer walls of the left and right ends of the metal telescopic frame 14, respectively. In this way, the metal telescopic frame 14 and the metal suspension rod 16 can be locked, so that the two are kept in the currently adjusted state for use, thus ensuring that the lifting hook 5 is always used at the adjusted height.
